At Hillingdon Hospitals , staff are among the most likely to say they have experienced physical violence from their colleagues, with the rate of 3.6% twice the national average of 1.8% for acute trusts.
And London North West Healthcare, which manages Ealing , Central Middlesex, and Northwick Park and St Mark's hospitals, was among the worst trusts in the country for physical violence from managers.
Of the staff working there, 1.5% reported experiencing physical violence from a manager, compared with the national average of 0.6%.
Across the NHS, the proportion of staff experiencing no physical violence rose slightly, from 87% in 2014 to 87.5% last year.
Ambulance crews are the most likely to be subjected to violence and abuse, with 28.9% of paramedics, 59.9% of ambulance techs and 62% of emergency care assistants saying they had been physically assaulted.
A spokeswoman for The Hillingdon Hospitals said: "The trust has a zero tolerance approach to violence and aggression, and it is unfortunate that a small proportion of staff at the trust state that they have experienced physical violence from their colleagues.
"The trust will be carrying out further analysis of the data to identify if the alleged violence is occurring in certain parts of the Trust, or whether this is more generic."
She added that it would also write to staff reminding them of its zero-tolerance approach to violence and would ask staff to report any incidents at the trust, where she said there is a 24-hour on-site security presence.
Peta Hayward, director of human resources at Chelsea and Westminster Hospital NHS Foundation Trust, said: “The overall results of the staff survey are encouraging, although clearly we are disappointed by the percentage of staff who have experienced bullying, harassment or abuse.
"We always encourage staff to report inappropriate behaviour, and for this not to be regarded as acceptable. It is therefore good to see that both Chelsea and Westminster and West Middlesex hospitals are above average in terms of the percentage reporting experience of harassment, bullying or abuse."
She added that staff had received training about what was considered unacceptable behaviour and the support available to victims of abuse of violence, and that the trust planned to review where specific interventions could help key staff groups or departments reporting higher levels of abuse.
